摘要
轨道交通供电系统在工作时会产生大量的谐波。谐波的存在对轨道交通的运行存在很大的安全威胁。轨道交通普遍采用24脉波整流机组。介绍了24脉波整流机组工作原理,并分析了其谐波特点。对三电平有源滤波器的拓扑结构和三电平矢量控制算法进行了说明。在Matlab/Simulink建立仿真模型,研究了有源滤波器对24脉波整流机组非特征次谐波的补偿作用。
Rail transit power supply system generates a lot of harmonics while in working, which are a big threat to rail transit security. At present, urban rail transit normally adopts the 24-pulse rectifier unit, its working principle and the harmonic characteristics are analyzed first in this pa-per. Then the three-level active power filter （APF） topolo-gy and three-level vector control algorithm are described, a Matlab/Simulink simulation model is established, the com-pensation to the non-feature harmonics of active filter 24-pulse rectifier unit is studied.
